I know a couple of people with children at Carlton. They are very happy with it. Their only problem is that it isn't a local school to them, and is a pain to get to, so they would move their child if a nearer place came up. Although another family chose to keep their child at Carlton in the same circumstances as they loved it so much. I visited and thought the staff were amazing but the reception classroom was a bit tired. Although I think it's had some building work done to it recently?
So you might find you are local, but that not all of the intake are. Might make it a bit more difficult for playing after school?
I also visited Rhyll and didn't dislike it, although it seemed a bit odd not to be shown round by the head. I think a member of office staff showed me round. I know a family who removed their child from there when a place came up elsewhere. Although it's not supposed to be popular, we were never offered a place( stayed on waiting list of all schools for various reasons) and it's reasonably close to us.
They aren't popular mc schools, and some people will go the church route to avoid. From what I have seen off all local schools the type of education is very similar wherever you are. Check their results, on par, and often better than more sought after schools.
Carlton has a burger van parked outside it, well it did. That really annoyed DP and put him off it.
Have you visited them both? That was something else that put me off- I tried for 2 years to visit Carlton and it seemed impossible! We finally did get to visit, but I was fed up by then.
